Hi,

How does one generate a new Windows GUID from within Java?

I have been looking at the API available in .NET for this, and it involves a call to System.Guid.NewGuid() to get a new GUID generated. Does Java offer something similar for Windows environment?

Thanks.

Java offers no platform-specific APIs, period; so no, there's no built-in way to do this. There are, however, two options you can pursue: first, if there's a Windows executable that generates a GUID and prints it, you could run this program using Java's java.lang.Runtime.exec() method, and capture the output.

Another option is to use the JNI, the Java Native Interface, which lets you implement the body of a Java method using native (i.e., C/C++) code.
